Setup Applets in Firefox 1.x/2.x/3.x

These instructions install the Java Plug-In and may require System Administrator access to configure Firefox 1.x, 2.x, or 3.x to run NeXtMidas applets:

  1. Download the recent version of the Java Development Kit (JDK) from http://java.sun.com and install the JDK as directed.
  2. (Linux/Solaris Only) Provide Firefox with access to the Java Plug-In library:
    1. cd into the browser's plugins directory located in the Firefox installation:
      /opt/firefox/plugins (This requires System Administrator access) Or
      ~/.mozilla/plugins (Changes will only be effective for user)
    2. Locate the appropriate plugin library.
        For older Firefox versions (pre-3.6), use the plugin which is the only file in the $JAVAHOME/jre/plugin/i386/ns610 directory. $JAVAHOME is the JDK's installation directory, i386 is the system platform type (use sol on Solaris), and ns610 is the browser class (ns for Netscape/Mozilla followed by a semi-arbitrary version number).
        For Firefox 3.6 and later, use the plugin:
           32-bit Firefox:  $JAVAHOME/jre/lib/i386/libnpjp2.so
           64-bit Firefox:  $JAVAHOME/jre/lib/amd64/libnpjp2.so
          NOTE: A 32-bit Firefox requires a 32-bit JDK plugin
    3. Create a symbolic link with "ln -s library" (library is the absolute path of the library found in the previous step). The link must be a symbolic link; you can not make a hard link or copy the library.
    4. For more help, see Mozilla Support
  3. Start Firefox.
  4. Select Edit/Preferences.
  5. Click on Web Features, then verify the "Enable Java" and "enable JavaScript" are selected.

Note: If you only use NeXtMidas as an applet on Windows, then download the Plug-In from http://www.java.com and install it separately from the rest of JDK.
